STEAM-BOILER.

SPECIFICATION formingpart of Letters Patent No. 561,292, dated June 2,1896.

Application filed February 28, 1895. Serial No. 539,975. (No model.)

T at whom, it may concern:

Be it known that I, GEORGE IV. SWARTZ, a citizen of the United States,residing at Florence, in the county of Lauderdale and State of Alabama,have invented certain new and useful Improvements in Steam-Boilers, andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, ref erence being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

steam-boilers, and refers particularly to what are known as verticalboilers; and one object of my invention is the provision of asteanrboiler which will present a great area or amount of surface to theaction of the heat to insure the generation of a vast amount of steam.

Another object of my invention is the provision of a steam-boiler whichwill permit ready and easy access to all its parts for the purpose ofcleaning or repairing.

Another object of my invention is the provision of a steam-boiler whichwill insure a perfect circulation of the water, which will be compact,simple, and durable, and entirely safe and practical.

To attain the desired objects the invention consists of a verticalsteam-boiler embodying novel features of construction and combination ofparts for service substantially as disclosed herein. I

In order that the details of construction of my steam-boiler may beunderstood and its numerous advantages be fully appreciated, I haveillustrated in the accompanying drawin gs a steam-boiler constructed inaccordance with my invention.

Figure 1 represents an elevation of my steam-boiler with parts brokenaway to more clearly illustrate the details. Fig. 2 represents a similarview of my steam-boiler with slight modifications in construction, andFig. 3 represents a detail view of a manner of connecting theoir-culatingpipe.

The numeral 1 designates the casing or housing of my improvedsteam-boiler, which maybe constructed of masonry or of sheet Myinvention relates to improvements in metal, having the discharge-pipe 2at its upper portion, the ash-pit 3 in its lower side, and the retort 4,having the door 5, above said ash-pit. Arranged centrally within thecasin gis the cylinder 6, having at its upper end the dome 7, from whichleads the pipe 8, and at its lower end the cap 9, said cap having anopening to permit access to the cylinder for removing foreign mattertherefrom, and said opening is provided with a screwcover 11. Enteringsaid cap is the feed-pipe 12, having the blow-off pipe 13, provided witha cook 14:, as shown by Fig. 1. This pipe 13, which communicates withthe pendent part 10 of the cylinder 6 and which is provided with theblow-off cook 14, is for the purpose of drawing off the water from thecyl' inder 6 by opening the cook 14 preliminary to cleaning out thesediment which may become deposited in the bottom of the cylinder 6.After the water shall have been drawn off through the pipe 13 and thecook 14 the cap or hand-hole in the side of the pendent part 10 can beremoved to permit access to be had to the cylinder 6.

The cylinder 6 is provided with a series of vertically-disposed openings15, the walls of which openings 15 are screw-threaded to receive thescrew-threaded inner ends of the horizontal radial circulating-pipes 18,having their ends extending through the casing and provided withdetachable caps 10. The circulating-pipes are arranged out of line andextend from the cylinder after the manner of the spokes of a wheel, andthus cover a vast amount of space and insure a thorough circulation ofthe water. Leading from the cylinder are the pipes and 21, whichcommunicate with the water-column 22, provided with the gage 23, thepurpose of which is well known.

, In the modified construction of my steamboiler shown in Fig. 2 Iemploy the additional circulating-pipe 24, which is connected to thepipes 18, which lead from the cylinder. I also provide the pipes and 21which lead to the water-column 26, having the gage 27, and I furtherprovide the pipe 13 which leads from one of the ciroulating-pipes 18 tothe pipe 21 as clearly shown, and forms in this instance acirculating-pipe. It will thus be seen that I provide in addition to thehorizontal circulating-pipes 18 the vertical circulating-pipes 24 and 13as clearly shown in Fig. 2.

In the detail View Fig. 3 I use, in connection with the horizontalradial circulatingpipes 18, the curved circulating-pipes 29, which areconnected to the said pipes 18 by means of the four-Way coupling 28, andby this means I secure a perfect circulation of the water, as isevident.

A steam-boiler consisting of the casing, the Vertical cylinder therein,the horizontal or lateral pipes connected to the cylinder and extendingthrough the casing, the caps se- I 5 forming a circular and horizontalset of eir- 2o culating-pipes.

In testlmony whereof I affix my signature in presence of two witnesses.

GEORGE W. SWARTZ.
